Based on its configuration, volume indicators can report the activity in quarter-hourly, half-hourly, hourly or daily chunks referred to as its granularity. Once you generate a forecast, you have the opportunity to view and modify the forecasts for future weeks at these different levels of granularity. You modify the volume indicators to:
· Ensure your volume forecasts are accurate
· Adjust the forecast to account for any last minute campaigns or events that might impact the interaction center’s business continuity but was not within the historical data upon which the forecast was generated
You modify a forecast using the View/Modify Forecast page of the Forecasting iView accessed through the Interaction Center Manager’s portal by entering Workforce Management ® Forecasting ®View/Modify Forecast. See View/Modify Forecast Page for more information.
